Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of digital imaging devices for logging cuttings, and is an on-line digital imaging system for logging cuttings. Background Art
[0002] During the oilfield drilling process, cuttings fluorescence logging is an important means to obtain first-hand geological data. In traditional fluorescence logging, cuttings are irradiated with a fluorescent lamp, and technicians qualitatively describe and judge the oil-bearing property of cuttings based on vision and experience. However, it is difficult to avoid information loss caused by subjective factors through naked-eye observation. In addition, oil-bearing cuttings will also lose information due to volatilization and weathering in the air. Therefore, generally, after the cuttings are taken out for a long time, it will be impossible to re-describe the fluorescence of the cuttings. Moreover, due to differences in subjective factors among people, it often affects the objective evaluation of geological structure characteristics, reducing the accuracy of intelligence data. Currently, the technology that can solve the above problems is the cuttings image acquisition and analysis technology. This technology determines the percentage content by the ratio of the number of fluorescent pixels to the total number of pixels in the viewing field. The actual area sizes reflected by the pixels are the same, and the judgment is relatively accurate and objective, thus achieving the transformation from qualitative to quantitative.
[0003] With the development of drilling technology, especially after the wide application of PDC bits, the drilling speed has increased, and the cuttings drilled out are very fine, which requires higher skills and physical strength from logging personnel. Manual logging operations face greater pressure, and problems are likely to occur in terms of the continuity, accuracy of sample collection, and reliability of identification. At the same time, with the increase in the work intensity of cuttings sampling, cleaning, and description at the drilling site, the cuttings fluorescence information is likely to be insufficient or inaccurate.

The right cross slide 12 drives the finger cylinder gripper 13 to move to the left end of the right conveyor belt 10, and then moves the rock cuttings container and places it on the upper side of the vibration unit 1. After the vibration unit 1 works for a certain period of time, the rock cuttings sample in the rock cuttings container is vibrated and leveled. Then, the right cross slide 12 drives the finger cylinder gripper 13 to move the rock cuttings container on the upper side of the vibration unit 1 to the right end of the left conveyor belt 2. When there is no rock cuttings container in front of the proximity switch, the right conveyor belt 10 starts to work. The left conveyor belt 2 conveys the rock cuttings container from right to left through the wet fluorescence unit 3, drying unit, cooling unit and dry fluorescence unit of the rock cuttings in sequence, and completes the processes of wet fluorescence, drying, cooling and dry fluorescence of the rock cuttings in sequence. After the dry fluorescence is completed, the left conveyor belt 2 stops working. The operator puts the rock cuttings container into the recycling box 4, and then the video recording work of the rock cuttings sample can be completed.
